Last night when I was adding the last of the chrysalis to the aquarium I noticed this particular chrysalis's back end was extremely wiggly. It was intersting for me to watch this. I've never seen any of them do this in all the years I've working on this project.
Then these two were the last to go into the aquarium and this is what I recorded. I'm wondering why these two are as active as they are and why just this end of the chrysalis? Any thoughts?
